It effectively breaks down ammonium and nitrite, utilizing specialized cleaning bacteria. Sera marin bio reefclear, a product of Sera bio technology designed for marine aquariums, works to eliminate ammonium and nitrite with the aid of these beneficial bacteria. The inclusion of mineral volcanic rock helps to eliminate harmful substances, efficiently binds turbidity, and offers a surface for the cleaning bacteria to thrive. This ensures your water is healthy, clear, and biologically active. **Recommended dosage:** Shake well for 10 seconds before applying and then dose right away! A brief, milky cloudiness is expected and indicates the product is working. Depending on the level of impurities in your water, turbidity should clear up within 4 to 24 hours, leaving your water crystal clear. **Dosage for setting up the aquarium:** Use 1 scoop* of Sera marin bio reefclear for every 25 liters of aquarium water. Once ammonium levels are undetectable (for instance, confirmed with the Sera ammonium/ammonia test), it’s safe to introduce your aquatic animals. **Dosage for an established aquarium:** Administer 1 scoop* of Sera marin bio reefclear per 25 liters of aquarium water once a week. **Dosage after water changes or filter cleaning:** Use 1 scoop* of Sera marin bio reefclear for every 25 liters of aquarium water. *1 measuring cup (10 ml) should be filled to the outer line.Shipping Notes

Good boot sock

Used these for over a year now. They cover your calf and really don’t move from that spot. Very comfortable.
